ABSTRACT:
A magnetic recording and reproducing apparatus using a pilot signal control system is adapted such that a cue signal (51) is recorded in a cue track (50) provided besides a video signal track (52) when a magnetic tape (7) is temporarily stopped during the recording operation and is moved in the backward direction by a predetermined amount, and when the temporary stop is cancelled and the magnetic tape is moved in the forward direction, the cue signal (51) is reproduced and the recording operation is restarted responsive to the reproduced cue signal. Preferably, after cancellation of the temporary stop until restart of the recording operation, control is made such that coincidence of the frequency and phase of the reproduced pilot signal and those of a pilot signal to be recorded is established.
